Divine Comedy

Gustave Doré's engravings illustrated the Divine Comedy (1861–1868); here Charon comes to ferry souls across the river Acheron to Hell.

The poem begins on the night before Good Friday in the year 1300, "halfway along our life's path" (Nel mezzo del cammin di nostra vita). Dante is thirty-five years old, half of the biblical lifespan of 70 (Psalms 89:10, Vulgate), lost in a dark wood (understood as sin),[25][26][27] assailed by beasts (a lion, a leopard, and a she-wolf) he cannot evade and unable to find the "straight way" (diritta via) – also translatable as "right way" – to salvation (symbolized by the sun behind the mountain). Conscious that he is ruining himself and that he is falling into a "low place" (basso loco) where the sun is silent ('l sol tace), Dante is at last rescued by Virgil, and the two of them begin their journey to the underworld. Each sin's punishment in Inferno is a contrapasso, a symbolic instance of poetic justice; for example, in Canto XX, fortune-tellers and soothsayers must walk with their heads on backwards, unable to see what is ahead, because that was what they had tried to do in life:

they had their faces twisted toward their haunches
and found it necessary to walk backward,
because they could not see ahead of them.
... and since he wanted so to see ahead,
he looks behind and walks a backward path.[28]

Allegorically, the Inferno represents the Christian soul seeing sin for what it really is, and the three beasts represent three types of sin: the self-indulgent, the violent, and the malicious.[29] These three types of sin also provide the three main divisions of Dante's Hell: Upper Hell, outside the city of Dis, for the four sins of indulgence (lust, gluttony, avarice, anger); Circle 7 for the sins of violence; and Circles 8 and 9 for the sins of fraud and treachery. Added to these are two unlike categories that are specifically spiritual: Limbo, in Circle 1, contains the virtuous pagans who were not sinful but were ignorant of Christ, and Circle 6 contains the heretics who contradicted the doctrine and confused the spirit of Christ.[30]

Having survived the depths of Hell, Dante and Virgil ascend out of the undergloom to the Mountain of Purgatory on the far side of the world. The Mountain is on an island, the only land in the Southern Hemisphere, created by the displacement of rock which resulted when Satan's fall created Hell[31] (which Dante portrays as existing underneath Jerusalem[32]). The mountain has seven terraces, corresponding to the seven deadly sins or "seven roots of sinfulness."[33] The classification of sin here is more psychological than that of the Inferno, being based on motives, rather than actions. It is also drawn primarily from Christian theology, rather than from classical sources.[34] However, Dante's illustrative examples of sin and virtue draw on classical sources as well as on the Bible and on contemporary events.

Love, a theme throughout the Divine Comedy, is particularly important for the framing of sin on the Mountain of Purgatory. While the love that flows from God is pure, it can become sinful as it flows through humanity. Humans can sin by using love towards improper or malicious ends (Wrath, Envy, Pride), or using it to proper ends but with love that is either not strong enough (Sloth) or love that is too strong (Lust, Gluttony, Greed). Below the seven purges of the soul is the Ante-Purgatory, containing the Excommunicated from the church and the Late repentant who died, often violently, before receiving rites. Thus the total comes to nine, with the addition of the Garden of Eden at the summit, equaling ten.[35]

Allegorically, the Purgatorio represents the Christian life. Christian souls arrive escorted by an angel, singing In exitu Israel de Aegypto. In his Letter to Cangrande, Dante explains that this reference to Israel leaving Egypt refers both to the redemption of Christ and to "the conversion of the soul from the sorrow and misery of sin to the state of grace."[36] Appropriately, therefore, it is Easter Sunday when Dante and Virgil arrive.

The Purgatorio is notable for demonstrating the medieval knowledge of a spherical Earth. During the poem, Dante discusses the different stars visible in the southern hemisphere, the altered position of the sun, and the various time zones of the Earth. At this stage it is, Dante says, sunset at Jerusalem, midnight on the River Ganges, and sunrise in Purgatory.

Paradiso, Canto III: Dante and Beatrice speak to Piccarda and Constance of Sicily, in a fresco by Philipp Veit.

After an initial ascension, Beatrice guides Dante through the nine celestial spheres of Heaven. These are concentric and spherical, as in Aristotelian and Ptolemaic cosmology. While the structures of the Inferno and Purgatorio were based on different classifications of sin, the structure of the Paradiso is based on the four cardinal virtues and the three theological virtues.

The seven lowest spheres of Heaven deal solely with the cardinal virtues of Prudence, Fortitude, Justice and Temperance. The first three spheres involve a deficiency of one of the cardinal virtues – the Moon, containing the inconstant, whose vows to God waned as the moon and thus lack fortitude; Mercury, containing the ambitious, who were virtuous for glory and thus lacked justice; and Venus, containing the lovers, whose love was directed towards another than God and thus lacked Temperance. The final four incidentally are positive examples of the cardinal virtues, all led on by the Sun, containing the prudent, whose wisdom lighted the way for the other virtues, to which the others are bound (constituting a category on its own). Mars contains the men of fortitude who died in the cause of Christianity; Jupiter contains the kings of Justice; and Saturn contains the temperate, the monks who abided by the contemplative lifestyle. The seven subdivided into three are raised further by two more categories: the eighth sphere of the fixed stars that contain those who achieved the theological virtues of faith, hope and love, and represent the Church Triumphant – the total perfection of humanity, cleansed of all the sins and carrying all the virtues of heaven; and the ninth circle, or Primum Mobile (corresponding to the Geocentricism of Medieval astronomy), which contains the angels, creatures never poisoned by original sin. Topping them all is the Empyrean, which contains the essence of God, completing the 9-fold division to 10.

Dante meets and converses with several great saints of the Church, including Thomas Aquinas, Bonaventure, Saint Peter, and St. John. The Paradiso is consequently more theological in nature than the Inferno and the Purgatorio. However, Dante admits that the vision of heaven he receives is merely the one his human eyes permit him to see, and thus the vision of heaven found in the Cantos is Dante's personal vision.

The Divine Comedy finishes with Dante seeing the Triune God. In a flash of understanding that he cannot express, Dante finally understands the mystery of Christ's divinity and humanity, and his soul becomes aligned with God's love:[37]

But already my desire and my will
were being turned like a wheel, all at one speed,
by the Love which moves the sun and the other stars.[38]

According to the Italian Dante Society, no original manuscript written by Dante has survived, although there are many manuscript copies from the 14th and 15th centuries – some 800 are listed on their site.[39]

The first printed edition was published in Foligno, Italy, by Johann Numeister and Evangelista Angelini da Trevi on 11 April 1472.[40] Of the 300 copies printed, fourteen still survive. The original printing press is on display in the Oratorio della Nunziatella in Foligno.

Although the Divine Comedy is primarily a religious poem, discussing sin, virtue, and theology, Dante also discusses several elements of the science of his day (this mixture of science with poetry has received both praise and criticism over the centuries[46]). The Purgatorio repeatedly refers to the implications of a spherical Earth, such as the different stars visible in the southern hemisphere, the altered position of the sun, and the various time zones of the Earth. For example, at sunset in Purgatory it is midnight at the Ebro, dawn in Jerusalem, and noon on the River Ganges:[47]

Just as, there where its Maker shed His blood,
the sun shed its first rays, and Ebro lay
beneath high Libra, and the ninth hour's rays

were scorching Ganges' waves; so here, the sun
stood at the point of day's departure when
God's angel – happy – showed himself to us.[48]

Dante travels through the centre of the Earth in the Inferno, and comments on the resulting change in the direction of gravity in Canto XXXIV (lines 76–120). A little earlier (XXXIII, 102–105), he queries the existence of wind in the frozen inner circle of hell, since it has no temperature differentials.[49]

Inevitably, given its setting, the Paradiso discusses astronomy extensively, but in the Ptolemaic sense. The Paradiso also discusses the importance of the experimental method in science, with a detailed example in lines 94–105 of Canto II:

Yet an experiment, were you to try it,
could free you from your cavil and the source
of your arts' course springs from experiment.

Taking three mirrors, place a pair of them
at equal distance from you; set the third
midway between those two, but farther back.

Then, turning toward them, at your back have placed
a light that kindles those three mirrors and
returns to you, reflected by them all.

Although the image in the farthest glass
will be of lesser size, there you will see
that it must match the brightness of the rest.[50]

A briefer example occurs in Canto XV of the Purgatorio (lines 16–21), where Dante points out that both theory and experiment confirm that the angle of incidence is equal to the angle of reflection. Other references to science in the Paradiso include descriptions of clockwork in Canto XXIV (lines 13–18), and Thales' theorem about triangles in Canto XIII (lines 101–102).

Galileo Galilei is known to have lectured on the Inferno, and it has been suggested that the poem may have influenced some of Galileo's own ideas regarding mechanics.[51]

Without access to the works of Homer, Dante used Virgil, Lucan, Ovid, and Statius as the models for the style, history, and mythology of the Comedy.[52] This is most obvious in the case of Virgil, who appears as a mentor character throughout the first two canticles and who has his epic The Aeneid praised with language Dante reserves elsewhere for Scripture.[53] Ovid is given less explicit praise in the poem, but besides Virgil, Dante uses Ovid as a source more than any other poet, mostly through metaphors and fantastical episodes based on those in The Metamorphoses.[54] Less influential than either of the two are Statius and Lucan, the latter of whom has only been given proper recognition as a source in the Divine Comedy in the twentieth century.[55]

Besides Dante's fellow poets, the classical figure that most influenced the Comedy is Aristotle. Dante built up the philosophy of the Comedy with the works of Aristotle as a foundation, just as the scholastics used Aristotle as the basis for their thinking. Dante knew Aristotle directly from Latin translations of his works and indirectly quotations in the works of Albert Magnus.[56] Dante even acknowledges Aristotle's influence explicitly in the poem, specifically when Virgil justifies the Inferno's structure by citing the Nicomachean Ethics.[57] In the same canto, Virgil draws on Cicero's De Officiis to explain why sins of the intellect are worse than sins of violence, a key point that would be explored from canto XVIII to the end of the Inferno.[58]

The Divine Comedy's language is often derived from the phraseology of the Vulgate. This was the only translation of the Bible Dante had access to, as it was one the vast majority of scribes were willing to copy during the Middle Ages. This includes five hundred or so direct quotes and references Dante derives from the Bible (or his memory of it). Dante also treats the Bible as a final authority on any matter, including on subjects scripture only approaches allegorically.[59]

The Divine Comedy is also a product of Scholasticism, especially as expressed by St. Thomas Aquinas.[60][61] This influence is most pronounced in the Paradiso, where the text's portrayals of God, the beatific vision, and substantial forms all align with scholastic doctrine.[62] It is also in the Paradiso that Aquinas and fellow scholastic St. Bonaventure appear as characters, introducing Dante to all of Heaven's wisest souls. Despite all this, there are issues on which Dante diverges from the scholastic doctrine, such as in his unbridled praise for poetry.[63]

Dante lived in a Europe of substantial literary and philosophical contact with the Muslim world, encouraged by such factors as Averroism ("Averrois, che'l gran comento feo" Commedia, Inferno, IV, 144, meaning "Averrois, who wrote the great comment") and the patronage of Alfonso X of Castile. Of the twelve wise men Dante meets in Canto X of the Paradiso, Thomas Aquinas and, even more so, Siger of Brabant were strongly influenced by Arabic commentators on Aristotle.[64] Medieval Christian mysticism also shared the Neoplatonic influence of Sufis such as Ibn Arabi. Philosopher Frederick Copleston argued in 1950 that Dante's respectful treatment of Averroes, Avicenna, and Siger of Brabant indicates his acknowledgement of a "considerable debt" to Islamic philosophy.[64]

In 1919, Miguel Asín Palacios, a Spanish scholar and a Catholic priest, published La Escatología musulmana en la Divina Comedia (Islamic Eschatology in the Divine Comedy), an account of parallels between early Islamic philosophy and the Divine Comedy. Palacios argued that Dante derived many features of and episodes about the hereafter from the spiritual writings of Ibn Arabi and from the Isra and Mi'raj or night journey of Muhammad to heaven. The latter is described in the ahadith and the Kitab al Miraj (translated into Latin in 1264 or shortly before[65] as Liber Scalae Machometi, "The Book of Muhammad's Ladder"), and has significant similarities to the Paradiso, such as a sevenfold division of Paradise, although this is not unique to the Kitab al Miraj or Islamic cosmology.[66]

Many scholars have not been satisfied that Dante was influenced by the Kitab al Miraj. The 20th century Orientalist Francesco Gabrieli expressed skepticism regarding the claimed similarities, and the lack of evidence of a vehicle through which it could have been transmitted to Dante. Even so, while dismissing the probability of some influences posited in Palacios' work,[67] Gabrieli conceded that it was "at least possible, if not probable, that Dante may have known the Liber Scalae and have taken from it certain images and concepts of Muslim eschatology". Shortly before her death, the Italian philologist Maria Corti pointed out that, during his stay at the court of Alfonso X, Dante's mentor Brunetto Latini met Bonaventura de Siena, a Tuscan who had translated the Kitab al Miraj from Arabic into Latin. Corti speculates that Brunetto may have provided a copy of that work to Dante.[68] René Guénon, a Sufi convert and scholar of Ibn Arabi, rejected in The Esoterism of Dante the theory of his influence (direct or indirect) on Dante.[69] Palacios' theory that Dante was influenced by Ibn Arabi was satirized by the Turkish academic Orhan Pamuk in his novel The Black Book.[70]

In addition to that, it has been claimed that Risālat al-Ghufrān ("The Epistle of Forgiveness"), a satirical work mixing Arabic poetry and prose written by Abu al-ʿAlaʾ al-Maʿarri around 1033 CE, had an influence on, or even inspired, Dante's Divine Comedy.[71][72]

The Divine Comedy has been translated into English more times than any other language, and new English translations of the Divine Comedy continue to be published regularly. Notable English translations of the complete poem include the following.[83]
